Circuit Schematic Mini Selfie Light based on LM555 IC

Eltronicschool. - Now, there are many people want to immortalize their special moment like when they studying, travelling, shopping, etc using their smartphone. One activity that their done is called with selfie. In this time we will show you one electronic circuit schematic designed specially to support this selfie.

This circuit schematic is called with Circuit Schematic Mini Selfie Light based on LM555 IC like in Figure 1 below that presented by Electroschematics.com site. In here beside we will show you Circuit Schematic Mini Selfie Light based on LM555 IC, we also will give you global description and then give you link to read more this circuit from original source..

Description

Circuit schematic like in figure 1 above is Circuit Schematic Mini Selfie Light based on LM555 ICHere is the circuit of a “Selfie Light” for capturing beautiful selfies on your smartphone/tablet. The idea is an aftereffect of my frustration when I found that the front facing camera of my tablet would produce slightly blurred and underexposed photographs; it wasn’t up to the task of taking well-lit selfies in dark environments. This USB-powered portable LED-based light can be used with any smart phone/tablet offers a USB On- The- Go (USB OTG) feature. The amount of light emitted can be controlled, so there is no worrying that the light output will ever wash out the object’s face. Further, its overall dimensions can be reduced by employing chip (leadless) components in lieu of the traditional (leaded) components.
